【 摘 要 】

The Sm doped cerium dioxide films were prepared with cerium foils as raw materials by anodization in Sm(NO3)3-Na2C2O4-NH3•H2O-H2O-(CH2OH)2electrolyte. The anodic Sm doped cerium oxide film was heat treated at 550°C. The Sm doped cerium dioxide films were characterized with X-ray diffraction (XRD), energy-dispersive analyses of X-ray (EDAX), Fourier transform infrared (FTIR) techniques and scanning electron microcopy (SEM), respectively. The anodic Sm doped cerium oxide film is semi crystalline film. The heat treated anodic Sm doped cerium oxide film at 550°C has a structure of cubic fluorite. The doping of Sm is replacement doping or caulking doping. The Sm doped cerium dioxide film is porous film. The water, ethylene glycol and CO2are adsorbed in the anodic Sm doped cerium oxide film. The adsorbing water, ethylene glycol and CO2in the anodic Sm doped cerium oxide film are removed at 550°C. The Sm doped cerium dioxide film has strong absorption in the range of 1200 ∼ 4000cm-1.
